👉 Coated engineering refers to the process of applying a thin layer of material onto a substrate to enhance its properties or introduce new functionalities. This technique is widely used in various industries, including aerospace, automotive, electronics, and medical devices, to improve characteristics such as corrosion resistance, wear resistance, electrical conductivity, thermal stability, or biocompatibility. The coating can be made from materials like metals, ceramics, polymers, or composites, and the method of application can vary from physical vapor deposition (PVD) and chemical vapor deposition (CVD) to electroplating and sol-gel processes. By carefully selecting the coating material and process parameters, engineers can tailor the surface properties of components to meet specific performance requirements, thereby extending their lifespan and enhancing overall system efficiency.
